First Dana Bailey lost her mother to cancer. Then she lost her remains to a funeral parlor.

In a $750,000 Manhattan Supreme Court lawsuit, Bailey says she didn’t discover the urn she was given by Benta’s Funeral Home was empty until weeks after mom Barbara Betran’s funeral service.

Betran, 65, a special-education teacher from Morningside Heights, had died of cancer on Feb. 3, and her cremated remains were supposed to be placed in the urn before her funeral.

“We lost our mother twice,” Bailey said.

She said that after she and her siblings made the heartbreaking discovery, the funeral home offered to turn over the ashes, but the family refused “because they cannot be assured that they are the ashes of their mother.”

Jason Benta, a manager for the funeral home, said he had not yet seen the suit and could not comment on it.
